VLM output
A wet suburban intersection where standing water covers the low-lying road surface and partially submerges the base of the yellow-and-black bollards on the traffic island. Across the four frames the water gradually recedes, with the pooled area shrinking and more dry pavement and road markings reappearing, while parked cars remain stationary and no traffic passes.

Customer challenges
Operators learn that a road has flooded from scattered calls and reports, long after the water has risen.
Deciding when a road is safe to reopen depends on someone driving out to look.
A blocked drain looks the same as a slow-draining road on a status board, so the real fault goes unnoticed for hours.
Repeat flood locations are known informally by experienced staff and are hard to prove when maintenance budgets are set.
Customer benefits
Teams see flooding start and recede as it happens, so closures and reopenings are timed on evidence.
Crews are sent to the sites where water is not clearing, instead of checking every reported location.
Drainage faults surface as an alert rather than as a pattern someone notices later.
Maintenance planning is backed by a record of which roads flood again and again.
